BRITISH FOSSIL ELEPHANTS. 
same collection, from the Iron Pan, Forest Bed, Bacton, is a portion of a right upper 
tooth, showing a well-marked pressure-scar on the heel, and contains 11 x in 8x3^ 
inches, and five ridges in 3J inches. None of the digitations are worn out; nevertheless, 
the plates are thick, and there is an excess of cement; altogether it may be fairly corre¬ 
lated with the preceding. 
No. 33,365, B. M., is a fragment of a right ramus of a mandible from FIappisborough. 
It contains about eight ridges of the first true molar with an entire second true molar 
behind it; the first four ridges of the latter have been invaded. The diasteme is 
preserved. This jaw has been broken across at the symphysis in front, and in a line 
with the heel of the second true molar behind. 
The second molar is considerably arcuated and holds x 10 a? in 8jx 3^ inches. There 
is about an inch to every ridge. It is broad behind, being 3’4 inches in width. The 
crown shows enamel free from crimping, and has the usual excess of cement observed iii 
these uncrimped teeth, whose external margins present some roughening and channelling. 
The breadth of crown, the length, and the small height are evident characters as 
compared with the varieties of E. antiquus; and the low ridge formula is assuredly 
significant, inasmuch as I have not met with the same in any second true molar of the 
latter species. 
With reference to the characters of the ramus. The mental foramina are two in 
number. One at a distance of L2 inches from the margin of the diasteme, the other 
2*2 inches distant and a short way above the last. 
The usual foramen inside the spout is about 1 # 4 inches from the margin. 
The diasteme slopes at about an angle of 45°. The thickness of the jaw at the base 
of the coronoid is 6j inches. The rostrum is wanting. In the rather reclinate diasteme 
the jaw differs from that of E. antiquus, and is broadly distinct, of course, from that of E. 
primigenius. 
A detached left lower molar (PI. XXIII, figs. 1 and 1 a), No. 33,343, B. M., also 
from the Norfolk coast, holds apparently a formula of x 9 x. The anterior talon is 
like a plate, and so is the posterior, excepting a small prominence on its posterior 
surface. About five or six ridges of this tooth are invaded. It is somewhat arcuated, 
with a double anterior fang followed by a coalescence posteriorly. The length is 8jX 
and contains eight ridges in about 5'2 inches. It presents the same characters as the 
last, with which it may fairly claim relationship. 
A characteristic specimen of evidently a second true molar in a fragment of a jaw was 
discovered by Mr. Alfred Savin at Overstrand, Cromer; No. 37 of his collection. It 
is a right upper molar with a well-marked pressure-scar on the heel. All the plates are 
jn wear. The anterior fang is preserved, but the first ridge has been ground away, leaving 
eleven plates and a posterior talon in 8 X 3£ inches. There are five plates in 3jr inches i 
The uncrimped enamel, the channelling of the latter, the excess of cement, its dimensions 
and low ridge formula, seem to me to place it with the foregoing.
